This article will explain in detail the example analysis of the routing table in Linux. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Detailed introduction of the routing table of Linux

Execute the route command under Linux

[root@localhost backup] # route-nKernel IP routing tableDestination Gateway Genmask Flags Metric Ref Use Iface0.0.0.0 192.168.0.1 0.0.0.0 UG 1000 enp0s3192.168.0.0 0.0.0.0 255.255.255.0 U 10000 enp0s3192.168.122.0 0.0.0.0 255.255.255.0 U 00 virbr0 [root@localhost Backup] # routeKernel IP routing tableDestination Gateway Genmask Flags Metric Ref Use Ifacedefault gateway 0.0.0.0 UG 100 00 enp0s3192.168.0.0 0.0.0.0 255.255.255.0 U 100 00 enp0s3192.168.122.0 0.0.0.0 255.255.255.0 U 00 0 virbr0

2. Detailed explanation of route command

1. Command syntax

Route [- n] options and parameters:-n: displays the hostname as IP

2. Query result analysis

Destination: it actually means Network. Gateway: the IP of the Gateway of the API. A value of 0.0.0.0 means no additional IP is required. Genmask: Netmask, combined with Destination to form a host or network. Flags: there are several flags that can represent the meaning of the network or host. U: indicates that the route is available. G: the representative needs to pass through Gateway to help deliver. H: represents that the row is routed as a host, not a network. Iface: it means interface.
